Research and Discussion on Increasing the Coincidence Rate of Water Injection Scheme

Abstract “Enough water injection, good water injection and effective water injection” is the foundation of water flooding to develop oil fields, and whether the water injection scheme is reasonable and effective is an important symbol of effective water injection. Affected by complex reservoir types and geological conditions, the coincidence rate of water injection schemes in some oilfields is low. In this paper, based on effective water injection, guided by the problems existing in the development of various oilfields, the overall adjustment idea is formulated, and then the injection-production status of single well, single layer and single sand body is analyzed accurately and carefully by comprehensive application of dynamic and static data, so as to implement accurate water distribution. At the same time, cooperate closely with production and management units to ensure timely discovery, adjustment and tracking of problem wells, and strengthen the work of each node, so as to improve the compliance rate of water injection scheme, realize effective water injection in oilfield and improve oilfield development effect.
